On March 7, B1A4's oldest member CNU went through his commencement ceremony after successfully completing basic training at the 27th Infantry Division base camp. Gongchan expressed to fans on the group's official fan cafe, "I went by CNU hyung's ceremony. I was watching CNU hyung at the gym, and I couldn't keep my eyes off of him. He was so cool and looked reliable and dignified. I really worried about my CNU hyung, and I'm a lot less worried now. I think BANA don't have to worry much either."

He continued, "I hope our awesome CNU hyung goes well and doesn't get hurt. Let's see each other again. I'll miss you a lot."
